Hello,
I’m working on friends bike with Sram X5 derailler.
Noticed inner cage plate been loose and took out pulleys for cleanup.
What I don’t understand is how bearing is suppose to work. As you can see on photo, there is no center barrel which sets distance of steel plates and act as bearing surface. I have multiple worn out Shimano pulleys, but parts from them are 1 mm too short to use.
Have new, original from distributor, unopened X5 replacement set. I don’t see this barrel part here ether.
Anyone know how this was designed to work?
In Sram spare parts catalogue similar part, I believe to missing, is used for offset upper pulley on upper left, but I’m working with n. 3 style pulley.
Thanks,
Michal
The only way it works is if the bolt itself is the bushing and the threads bottom out on the back plate before it pinches the two cover plates into the jockey wheel, effectively locking it.
Bolt is too small to be effectively shaft and pinches cover plates to locking jockey wheel.
Also that way there would still be inner plate rattling around as screw head is just countersink.
I found contact form and what a bunch o clowns (we screw up, you buy more parts from us).
They don’t include “center sleeve” witch X5 replacement pulleys. You should reuse worn out part.
Parts not available, willing to downgrade, too bad.
I will be machining my own sleeves and consider aftermarket pulleys as first option for future with SRAM.
